These sourdough chocolate chip cookies are soft and chewy with golden edges, a rich buttery flavor, and just the right hint of tang from the starter. Not only is this recipe a delicious way to use up extra sourdough discard, but it also creates a depth of flavor you can’t get with a regular cookie.

FAQ’s
Can I use sourdough discard for these cookies?
Yes! This recipe is perfect for using up extra sourdough discard. The discard adds a subtle tang and richer flavor without making the cookies taste sour. This recipe was also created to use discard, but active starter could be used too.
Do I have to long-ferment the cookie dough?
No, you can bake the dough right away for a quick treat, or let it chill overnight for a long ferment. The long-ferment option helps with easier digestion and creates an even deeper flavor. You can long ferment up to 48 hours.
What type of chocolate works best?
You can use any chocolate you love—semisweet chips or dark chocolate chunks are the best!
Why use sourdough discard in cookies?
Sourdough starter (or discard) adds moisture, enhances the flavor, and reduces waste. It gives the cookies a slightly tangy depth you won’t get in traditional chocolate chip cookies.
How should I store these cookies?
Keep the cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze the dough balls and bake them straight from the freezer when you need a fresh batch.
PSA: This is NOT The Bubbly Batch Microbakery Sourdough Chocolate Chip Cookie recipe! However, this was my (very close) runner up recipe when recipe testing for the bakery! If I were to ever shut the bakery down I would post the recipe on the blog, but for now the bakery recipe is proprietary information. Thank you for understanding!
